It is an educational technical channel, interested in the field of electronics and the Internet of things in general, through which I explain, review and review what is related to embedded systems
هي قناة تقنية تعليمية, تهتم بمجال الالكترونكس و انترنت الاشياء بشكل عام وأقوم من خلالها بشرح واستعراض ومراجعة ما يتعلق بالأنظمة المدمجة

module FT5302 i took it from an old mother board tabled, it's only known by one datasheet, i use I2C connection with raspberry Pi Pico, i view many videos no one talk about it and i take the challenge, at first i need to understand I2C how it's work, than how to connect it and pull up resistor... all staff about hardware, but when i move on in software and call the library and initialize the I2C part i got a bunch of data which i did not understand which is relative with capacitive touch reading x or y and addressig,
can you help me please Build a temperature control system based on Lab VIEW and Arduino MCU, connect a temperature sensor to the Arduino unit, let the user define a three levels of control as following: - Level 1 if temperature is less than 22 °C, a green LED should be turned ON. - Level 2: if temperature is more than 22°C and less than 30°C, a fan should be turned on to 50% of its max speed. -Level 3: if temperature is more than 30°C and less than 38°C, the fan should work at 90% of its max speed. - Level 4: if the temperature exceeds 38°C then turn a Red LED ON and a 5V buzzer at a IkHz frequency. store the temperature values in a file with a rate of one reading each minute.

hi .. ı have some problems about when using seri port communication and opencv robotic hand display .. display is freezing unfortunately . ı can not solve this problem .. you can do this as seen .. what can ı solve problem of freezing display ? .. thanx
